A device for distributing a signal to a display device is provided to prevent unnecessary power consumption in a power saving mode by selectively applying operation power according to an operation mode of the display device with a power control function in a signal distributor. A PSU(Power Supply Unit)(210) outputs operation voltage. A signal distributor(220) transmits a video signal to other display devices in response to the operation voltage. A control signal generator(230) outputs a control signal according to application of the video signal. A power controller(240) selectively provides the operation voltage to the signal distributor in response to the control signal. The power controller includes the first switch and the second switch. The first switch includes the first electrode connected to the PSU, the second electrode connected to the ground, and the third electrode connected to the control signal generator. The second switch includes the first electrode connected to the PSU, the second electrode connected to the signal distributor, and the third electrode connected to the first electrode of the first switch.
